Introduction
This booklet contains the mark schemes for the higher tiers tests (Tests A and B) and
the lower tier test (Test C). The pupil answer sheets will be marked by external
markers who will follow the mark schemes in this booklet, which are provided here for
teachers’ reference.
General guidance for markers
Please note that pupils should not be penalised if they record any information given in
the question or show their working. Ignore any annotation, even if in the answer
space, and mark only the answer. Accept an unambiguous answer written in the
stimulus box, or elsewhere on the page, but clearly attributable to the relevant
question.
General guidance for marking the written tests also applies to marking the mental
mathematics tests. In addition, please apply the following principles unless specific
instructions to the contrary are given in the mark scheme:
■ accept responses in words and/or figures,
eg 7 point 3, 4 hundred;
■ accept any unambiguous indication of the correct response from a given list,
eg circling, ticking, underlining;
■ accept unambiguous misspellings;
■ accept units that have been correctly converted to a different unit provided the new
unit is indicated. Where units have been given on the answer sheet, do not penalise
pupils for writing the units again;
■ accept responses with commas as spacers,
eg 50,000
but do not accept a point used as a spacer,
eg 50.000
